Pine Cobble Alumnus Give Students DNA Lesson

Pine Cobble students look at the sample of Tyler DeWitt's DNA (below; taken from cells inside his cheek) after his presentation on Feb. 27.

WILLIAMSTOWN, Mass. — Before Tyler DeWitt did a TED Talk, before he had a website and a YouTube channel, before he received his Ph.D. in microbiology from the Massachusetts Institute of Technology, before he taught high school chemistry and biology in both the United States and South Korea, before he was a National Science Foundation fellow, he was just a student at Pine Cobble School.

On Feb. 27, DeWitt returned to the private school from which he graduated in 1997. It wasn't his first time back; he actually spoke at the school's commencement ceremony in 2013 and helped facilitate a STEAM summer camp session in 2018. And as often as he can, he comes back to Pine Cobble to try to make science fun for this generation of students.

And so on Feb. 27, in front of the school's students who were as little as pre-K and kindergarteners and as big as eighth- and ninth-graders, DeWitt bounced around the room to give an energetic science lesson on a subject that could potentially be scary: DNA.

That's deoxyribonucleic acid, not something to do with the "appetite of dinosaurs," as one student suggested.

"You can see why people use the abbreviation," DeWitt said.

Using a combination of slides and audience participation, an energetic DeWitt walked the students through the meaning of DNA. DNA determines a person's traits or characteristics, like eye color or height, or even the characteristics of a plant, like what color flowers it has or how big its leaves are. DNA is found in every part of the body, in the nucleus of cells, he said, showing pictures of cells magnified to give the students a clearer idea of what he was talking about.

"They're so tiny that you need hundreds or thousands to see even one," he said.

The best science, of course, is hands-on, and so DeWitt came prepared to lead the students on an exploration of their own DNA. He wasn't able to do that during his presentation, as they ran out of time, but he demonstrated with his own body and assured the students he was providing their teachers the materials they needed to do the experiment back in their classroom.

This was after he assured the students the experiment would be painless, after one student suggested they would need needles to extract DNA.

"This is silly and fun and it doesn't hurt at all," he said.

Instead of drawing blood, he said, the best place to get DNA samples? A person's cheek, which he said was teeming with cells.

"Your cheeks have cells that are coming off all the time," he said.

And so, he got down to it: He told the students he was going to take a sip of water, swish the water around his mouth for 60 seconds to really loosen those cells, and then spit the water into a cup. Which he did, as the students counted up to 60 to time him. (They tried, but it was actually 48 seconds.)

"Now I have some spit here that's filled with cheeky cells," he said to a chorus of both giggles and "eews" from the students.

Those cheeky cells were transferred to a test tube, a chemical was added to help break open the cells, some regular rubbing alcohol was added to "let the DNA come out of the cells" … and then he let it sit for a few minutes before "long strings" started to "bubble out."

"Those are the DNA," he said.

He carried the test tube around to show all the students, and even held it as the students filed past him out of the room to go home for the day, buzzing about when they would get a chance to do their own swishing and spitting.

"That was amazing," one student said.

Watching them leave the school where he spent so many of his formative years, DeWitt said he comes back to Pine Cobble as much as he can. He said he appreciates the way the school is "all about creative learning," even more so now than he when we was a student in the 1990s.

"It's so cool," he said, adding that he loves seeing the students "excited and engaged" with science. "They have a lot of energy."

Puppets Teach Resilience at Lanesborough Elementary School

By Breanna SteeleiBerkshires Staff

The kids learned from puppets Ollie and a hermit crab.

LANESBOROUGH, Mass. — Vermont Family Network's Puppets in Education visited the elementary school recently to teach kids about being resilient.

Puppets in Education has been engaging with young students with interactive puppets for 45 years.  

The group partnered again with Bedard Brothers Chevrolet, which sponsored the visit. 

Classes filtered through the music class Thursday to learn about how to be resilient and kind, deal with change and anxiety, and more.

"This program is this beautiful blending of other programs we have, which is our anxiety program, our bullying prevention and friendship program, but is teaching children the power of yet and how to be able to feel empowered and strong when times are challenging and tough," said program manager Sarah Vogelsang-Card.

The kids got to engage with a "bounce back" song, move around, and listen to a hermit crab deal with the change of needing a new shell.

"A crab that is too small or too big for its shell, so trying to problem solve, having a plan A, B and C, because it's a really tough time," Vogelsang-Card said. "It's like moving, it's like divorce of parents, it's changing schools. It's things that children would be going through, even on a day to day basis, that are just things they need to be resilient, that they feel strong and they feel empowered to be able to make these choices for themselves."

The resiliency program is new and formatted little differently to each of the age groups.

"For the older kids. We age it up a bit, so we talk about harassment and bullying and even setting the scene with the beach is a little bit different kind of language, something that they feel like they can buy into," she said. "For the younger kids, it's a little bit more playful, and we don't touch about harassment. We just talk about making friends and being kind. So that's where we're learning as we're growing this program, is to find the different kinds of messaging that's appropriate for each development level."

This programming affirms themes that are already being discussed in the elementary school, said school psychologist Christy Viall. She thinks this is a fun way for the children to continue learning. 

"We have programs here at the school called community building, and that's really good. So they go through all of these strategies already," she said. "But having that repetition is really important, and finding it in a different way, like the puppets coming in and sharing it with them is a fun way that they can really connect to, I think, and it might, get in a little more deeply for them.

Vogelsang-Card said its another space for them to be safe and discuss what's going on in their life. Some children are afraid because maybe their parents are getting divorced, or they're being bullied, but with the puppets, they might open up and disclose what's bothering them because they feel safe, even in a larger crowd. 

"When we do sexual abuse awareness that program alone, over five years, we had 87 disclosures of abuse that were followed up and reported," she said. "And children feel safe with the puppets. It makes them feel valued, heard, and we hope that in our short time that we're together, that they at least leave knowing that they're not alone."

Bedard Brothers also gave the school five new puppets to use. Viall said the puppets are a great help for the students in her classroom, especially in the younger grades. 

"Every year, I've been giving the puppets to the students. And I also have a few of the puppets in my classroom, and the students use them in small groups to practice out the strategies with each other, which is really helpful," she said. "Sometimes the older students, like sixth graders, will put on a puppet show. They'll come up with a whole theme and a whole little situation, and they'll act it out with the strategies for the younger students. It's really cute, they've done it with kindergarteners, and the kids really like it."

Vogelsang-Card said there are 130 schools in Vermont that are on the waiting list for them to come in. Lanesborough Elementary has been the only Massachusetts school they have visited, thanks to Bedard Brothers. 

"These programs are so critical and life-changing for children in such a short amount of time, and we are the only program in the United States that does what we do, which is create this content in this enjoyable, fun, engaging way with oftentimes difficult subjects," she said. "Vermont is our home base, but we would love to be able to bring this to more schools, and we can't do this without the support of community, business funders or donors, and it really makes a difference for children."

The fourth-grade students were the first class to engage with the puppets and a lot of them really connected with the show.

"I learned to never give-up and if you have to move houses, be nervous, but it still helps," said William Larios.

"I learned to always add the word 'yet' at the end," said Sierra Kellogg, because even if she can't do something now, she will be able to at some point.

Samuel Casucci was struck by what one of the puppets talked about. "He said some people make fun of him if he dresses different, come from different place, brings home lunch, it doesn't matter," Samuel continued. "We're all kind of the same. We're all kind of different, like we have different hairstyles, different clothes. We're all the same because we're all human."

"I learned how to be more positive about myself and like, say, I can't do this yet, it's positive and helpful," said Liam Flaherty.

The students got to take home stickers at the end of the day with contact information of the organization.
